Qualcomm issued a document to introduce the Snapdragon Sound Snapdragon listening technology systematically

Today, Qualcomm issued a document to introduce the Snapdragon Sound Snapdragon listening technology systematically and said that more than 40 manufacturers have signed technical agreements with Qualcomm to support the commercial use of Snapdragon Sound technology. Products are coming to market one after another.

What is Snapdragon Sound?

Snapdragon Sound integrates Qualcomm's innovative technologies in audio, connectivity, and mobility to provide high-quality music, clear voice calls, and ultra-low-latency gaming audio experiences for smartphones, wireless earbuds, and headphones. With excellent connectivity and longer battery life.

What key technologies does Snapdragon Sound incorporate

  • The new generation of Snapdragon 8 mobile platform and Snapdragon 8 series mobile platform
  • Qualcomm FastConnect 6900, FastConnect 7800 Mobile Connectivity System
  • Qualcomm QCC514x, QCC515x, and QCC3056 series of Bluetooth audio SoCs, and the new Qualcomm S5 audio platform (QCC517x) and Qualcomm S3 audio platform (QCC307x)
  • Qualcomm Active Noise Cancellation (ANC) technology
  • Qualcomm aptX™ Adaptive supports aptX™ Lossless audio
  • Qualcomm aptX™ Voice Ultra Wideband Voice
  • Qualcomm Aqstic™ Audio Codec and Smart Speaker Amplifier (WCD938x and WSA883x)
  • Qualcomm Audio and Voice Communications Suite

What are the features of Snapdragon Sound?

Top quality sound

Snapdragon Sound uses leading Qualcomm aptX Adaptive technology and supports the new aptX Lossless audio, providing wireless earbuds and headphones with CD-quality 16-bit 44.1kHz lossless audio, 24-bit 48kHz through Bluetooth wireless connection and 24-bit 96kHz high-definition audio.

At the same time, with aptX Voice technology, Snapdragon Sound can support Bluetooth end-to-end ultra-wideband voice, through 32kHz sampling frequency audio to provide up to 16kHz smooth frequency response voice, bringing high-definition voice to Bluetooth headphones or earbuds. In addition, Snapdragon Sound includes all the features of Qualcomm's audio and voice communication suite, designed to provide mobile terminals with an ultra-clear voice call experience comparable to wired.

Ultra-low latency

Thanks to the new FastConnect 7800 mobile connection system supporting a series of advanced Bluetooth audio features, Snapdragon Sound can bring a game mode with audio latency as low as 68ms, support a stutter-free gaming experience and in-game voice chat, Make sure the audio is in sync with the player's view to make the game more immersive.

Robust connection

Snapdragon Sound can also achieve a gain of 4dB through Qualcomm High-Speed ​​Link modulation technology, and a further 2dB gain through Qualcomm aptX Adaptive technology. Reducing the number of retransmissions and shortening the air time can better support Wi-Fi coexistence and a more robust overall connection experience. Advanced modulation and coding techniques help improve end-to-end Bluetooth robust connectivity, range, stability, and immunity from interference.

Seamless experience

Snapdragon Sound supports fast pairing, as well as support for a range of voice assistants and the new Bluetooth Low Energy Audio (LE Audio) standard. It also brings the best power optimization for smartphones and earbuds by reducing over-the-air time and supporting DSP channels.
